APPLICATION OF INDUSTRY 4.0 TECHNOLOGY IN IMPROVING PLASTIC INJECTION PROCESSES IN A COMPANY IN THE MANAUS INDUSTRIAL HUB

Abstract

Lead time optimization ensures compliance with deadlines established with customers, which in turn promotes customer satisfaction and loyalty. In addition, reducing this time provides more efficient resource management, with direct impacts on reducing operating costs. This study aimed to implement Industry 4.0 technologies to improve plastic injection processes in a company in the Manaus Industrial Park (PIM), reducing manufacturing costs, accelerating the lead time for building devices, and optimizing the time for developing new products. The methodology collected data on the new production processes and assessed the impact of the technology on reducing manufacturing costs and improving lead time, through mapping the current process flow, analyzing production loss reports, and production performance data. The results show a significant reduction in lead time, that is, the time required to create these devices, which was reduced from 35 (thirty-five) to 9 (nine) days. 3D printing has also made it possible to create more complex and precise devices, with less material waste, contributing directly to cost reduction and increased product quality.
